mysql>
if the database name is long enough, the use operation can work normally. for example, I may use test, and I may use test; too.
Say, the bug appears if use a shorter-named database.
The bug get repeated when I tried to connect a lower version server (v4.1) via a 5.0.15 client (Solaris x86), so I think the bug has something to do with the client part.
How to repeat:
you may create a database which name is like kk, and maybe you need create a table.
try to connect the server:
$mysql -uyouname -p
then you can see mysql>
try use kk
mysql>use kk
you can see this operation works.
but when you type use kk;
mysql>use kk;
you can see something wrong, and the error message is:
ERROR 1049 (42000): Unknown database 'kk;'
Suggested fix:
something wrong with the client. check the codes and see what happens where use kk;
